You can manually mark any SQLsafe backup that is stored on your TSM Server as inactive using the command line interface (CLI). For more information about how to use the TSM commands and options in the CLI, see the usage statements in the CLI Help.
An example CLI code snippet that uses the expire command
SQLsafeCmd expire TSM -BackupFile c:\NW_full.safe -TSMHighLevel Backup -TSMLowLevel SQLSAFEDEV01_SQL2000_Northwind_Full_2005300847.safe -age 7 days.
TSM is case sensitive. Be careful when specifying the High Level and Low Level file set.
